DEVICE FOR APPLYING TRANSFER-STAMPS.

Application filed February 11, 1911.

To all whom it may concern:

Be it known that I, CHARLES Gr. RICHARD- soN, citizen of the UnitedStates, and resident of Springfield, Vermont, have invented certain newand useful Improvements in Devices for Applying Transfer-Stamps, ofwhich the following is a specification.

This invention relates to the art of applying transfer stamps commonlyknown as decalcomania stamps to various kinds of fabrics and is intendedto provide a convenient device for automatically transferring suchstamps to the fabric while the fabric is being passed through somefinishing machine, such for example as a cloth measuring machine. Inthis case the device is shown applied to the frame-work of a clothmeasuring machine adjacent to the table over which the cloth is fed tothe measuring roll.

In its essential features the device comprises a mechanism for feedingthe tape which carries the transfer stamps to be applied to the clothand cooperating pressing means which are so coordinated with the tapefeeding mechanism as to transfer each stamp successively topredetermined portions of the fabric, after the respective stamps havebeen fed into proper relationship to the fabric.

In the device illustrated in the accompanying drawings, the tape bearingthe series of transfer stamps is fed between the pressing or transfermembers in the same direction as the travel of the cloth by anintermittent feed to which is coordinated the movement of the pressingor transfer members.

In its general features the device comprises cooperating rolls betweenwhich the transfer tape and the cloth are fed or advanced, one of saidrolls being heated and being made movable toward and away from the otherroll, so as to intermittently press the tape against the cloth underproper conditions to transfer the same to the cloth.

In the accompanying drawings Figure 1 is an end elevation partly insection of the device constructed in accordance with the principles ofthis invention applied to a table of a cloth measuring machine. Fig. 2is a diagrammatic view showing the tape feed rolls and the presser rollsin their operative relationship to each other. Fig. 3 is a frontelevation of the device partly in section and partly broken away to showporl Specification of Letters Patent.

tions of the interior parts. Fig. 4 is a detail end elevation showingthe continuously rotating ring by which the mechanism for feeding thetape and moving the heated presser is intermittently actuated. Fig. 5 isan end elevation of the main frame of the device by which the movingparts and the shaft are supported. 6 is an end elevation showing theprincipal parts of a modified form of the invention in their operativerelationship.

In the practice of my invention according to the form illustrated in thedrawings I employ a central supporting frame or casting a which isprovided with a central bearing or journal at a to receive the mainshaft I) which shaft is continuously driven by the sprocket wheel Z)pinned to the outer end, either of which may receive its rotation bymeans of a sprocket chain 6 passing over a sprocket wheel 72 on the mainshaft of the measuring machine. This frame is rigidly secured to asuitable portion of the end frame 5* of a cloth measuring machine orother machine to which it may be applied by means of a bracket (4 At oneend the central boss or hub a of the frame a is provided with a radialweb a carrying a cylindrical flange a which forms the bearing for anintermittently rotated hollow gear 0 provided with an internal gear ring0'. Said gear 0 has its bearing in an annular groove or seat formed inthe periphery of the flange (1 at its end. The hollow gear 0 has aprojecting annular flange c which forms a hearing for a continuouslyrotating ring (Z which is loosely mounted on said annular flange 0 andwhich receives its rotation from an arm d whose hub (Z is pinned to theshaft Z), so that the arm (Z revolves continuously with the rotatingshaft 7). The ends of arm d overlap the ring (Z and prevent it fromslipping laterally off the bearing-flange which supports it.

I will now describe the driving connection between the arm (Z and thering (Z. As shown in Fig. 1 the ring (Z is provided with a pin or stud(Z upon which is clamped a split hub member d" of a quadrant shaped arm(Z the jaws of said split hub being drawn together by a bolt d so as tofirmly grip said pin or stud (Z The arm (Z is provided on its forwardside with a flat spring metal arm or finger (Z whose free end en a esthe hub cl' at its rear side so I b 7 that as the arm (Z revolves thespring d pushes with a yielding pressure against this I tact betweenthese two cam members. Af-

hub (Z thereby causing the ring (Z to rotate in a contra-clockwisedirection on the flange c by which said ring is loosely carried. The arm(Z is provided with an offset or shoulder (Z so disposed as to beengaged by the end of the arm (Z when the spring (Z is flattened orstraightened out against the forward face of said arm (Z.

The gear 0 is normally held against rotation by means of a pivoted brakearm c which is normally pressed into clamping or gripping contact withthe periphery of the gear 0 outside of its internal gear ring 0. Thebrake arm 0 is pressed normally against the periphery of said gear ringinto operative position by means of a spring 0 which is fastened to anappropriate portion of the main frame a as shown in Fig. 1. At its freeend the brake arm 0* is provided with a cam plate 0 adjustable by meansof screw 0 and which is arranged to be engaged by a projecting cam plate(Z formed on or carried by the arm or lever (Z Obviously when in thecourse of the rotation of the ring (Z and of the arm (Z carried therebythe cam plate (Z comes into contact with the cooperating cam plate 0 onthe brake arm 0 the latter will be forced out away from contact with theperiphery of the gear ring 0, so that said gear ring will be left freeto rotate. The intermittent rotation of the gear a, 0 is effected by aconnection between said gear and the continuously rotating ring (Z,which I will now describe.

Mounted in a recess or pocket formed in the interior face of the ring (Zis a loose block or clutch member (Z which is capable of being forcedinto gripping contact with the annular flange 0 which forms the bearingfor the ring (Z so as to cause said flange 0 and consequently the gear0, c which is integral therewith to rotate in unison with the ring (Z.This clutch block or gripping member is moved into clamping position bymeans of the pin or stud d, the side of which adjacent to the grippingmember (Z is cut away to leave a fiat or eccentric surface. Obviouslythe rocking of this pin or stud (Z about its axis serves to disturb theparallelism between the outside fiat face forming the back of thegripping member d and the flat face of the pin and acts to force theclutch or gripping member (Z into frictional engagement or grippingengagement with the periphery of the flange portion 0 of the gear 0. Therocking of the pin (Z is accomplished by the inward movement of the freeend of the arm (Z which is produced when the cam plate (Z rides over thecam plate 0 of the brake, there being both an outward movement of thebrake to render it inoperative and an inward movement of the arm orlever (Z as a result of the conter the cam plate (Z has passed by camplate 0 the spring (Z tends to return the clutch lever (Z to its normalposition thereby releasing the clutch member or block 6 while of coursethe spring 0 tends to re tract the brake 0* to its normal. operativeposition to stop the rotation of the gear 0.

The tape feeding mechanism comprises a roll 6 which is intermittentlyrotated by the gear 0 through the medium of a spur gear 6 mounted on theshaft of the roll 6. Two idler rolls 6 and c are mounted on the swingingarm or lever 6* in position to press upon or contact with opposite sidesof the roll a. The tape is passed from any conveniently placed reelbetween the rolls 6, e by which it is pinched and fed thence around themovable presser or transfer roll f and is then carried back betweenrolls 6, 6 so that roll 6 acts to feed one portion of the tape forwardand the transfer mechanism to pull or lead back the used portion of thetape after it has passed by the transfer roll. The mechanism fortransferring the stamps from the tape to the fabric comprisesessentially the heated roll 7 and the cooperating roll f which iscarried by a fixed stud or journal which projects over a longitudinalslot in the table (A in position to sustain the upward pressure of theheated roll 7 which is intermittently brought into contact with thecloth and tape from beneath the table and which presses them against theidler roll f. As it is preferred to bring the presser roll intooperative relationship or contact with the cloth and tape only for asuflicient length of time to transfer the interposed stamp to the clothat the particular desired point on the cloth, say in this case atintervals of one yard along its edge, I provide mechanism for affectingthis intermittent movement of the roll f toward and away from the cloth.To that end the shaft of the roll 7 is mounted in end brackets 7 whichare secured to the swinging arm which is pivoted at f This arm isoscillated about the center f by means of a wrist pin or crank pinsecured eccentrically to the shaft 6 and which passes through anelongated slot 7 formed in the free or swinging end of the arm f". Ihave shown secured to the brackets f a shield or guide 7 comprising acurved plate as shown in Fig. 2 which follows the contour of the roll alittle distance from its periphery and se yes as a guide to direct thetape around the roll so as to increase the area of contact between thetape and the roll f. In order that the roll 7 may rotate while it is incontact with the traveling cloth and the tape, 1 have secured to one endof this shafta spur gear f which meshes with the intermediate gear fcarried by the frame which in turn is driven by a spur gear f which isengaged and driven by the intermittently rotatable internal gear 0 thistrain of gearing maintains a continuous driving connection between thepresser roll 7 and the driving gear 0 substantially unaffected by theswinging movement of the roll into and out of contact with the cloth.

As would be understood from the foregoing the intermittent rotation ofthe presser roll or member f and the intermittent feed of the tapebearing the transfer stamps is accomplished by the same driving member,namely the gear ring 0'. This insures the feeding forward of the tape atthe same time that the roll is rotating in contact with the cloth sothat the tape and the cloth to be marked and the heated roll may alltravel with the same surface speed during the interval that they are inoperative contact or relationship. The position of the crank pin f issuch as to cause the lever i to maintain the roll f in contact with thecloth and the tape at the time that the internal gear 0 is beingrotated.

In Fig. 6 I have illustrated a modified form of the invention in which Iemploy a heated non-rotating plate instead of the rotating roll f, thecooperating parts being modified to some extent to meet this change inthe pressing or transfer member. In this form of the invention theswinging arm h is pivoted to swing about the center 7i and has anextension supporting the electrically heated presser plate 7& to whichcurrent is supplied by wires 72,. This arm is provided with an elongatedslot k which receives the eccentric or crank pin f mounted on the shaftZ), so that with each revolution of the shaft the presser is movedtoward and away from the cloth. The cooperating presser or transfermember h consists of a roll which has for a small arc of itscircumference a projecting concentric presser portion it so that uponeach complete rotation of the roll 7& the pressing portion 7L passesonce in contact with the cloth, the size and surface speed of said rolls[L4 and 71, being preferably such as to equal the surface speed of thecloth traveling over the table beneath it. Said roll it is positivelydriven by the belt h which transmits motion from the main shaft 6. Inthis case the tape feeding roll a is driven by means of the gear 2"meshing with the gear ring 0 which is driven in the manner alreadydescribed in relation to Fig. 1. A cooperating feed ro-ll serves topinch the tape against the roll 7; and from the pinching of these tworolls the tape is led over the idler roll 2' whence it travels acrossthe top of the heated presser 7L around the take-up roll which is drivenby the belt i from the main shaft the grip or feed of said roll i beingmaintained by a light presser roll i mounted on the swinging arm 6 whichis normally pressed toward the roll i by the spring 6 This roll 2' isrotated continuously but its contact grip on the tape is so light thatit will not tear the tape when the tape is held against travel ormovement. The feeding rolls 1', 2' control the feed of the tape by theirintermittent rotation derived from the internal gear 0 while the roll 77serves to keep the tape taut throughout the whole operation.
